Digital Soil Hardness Tester Manual
Digital soil hardmeter includes a variety of specification for user’s selection. Users can select the appropriate specification of instrument according to the value of the force of the tested products. The scientific use of test range is 10%-100% of the full range. The measuring department is not recommended to use the 1% or less of the full range of the instrument.
1、High-precision and high-resolution: large-screen LCD display, with backlight function (backlight for night use), and positive, inverted reverse function of digitals on the screen.
2、Has a battery capacity display: divide into 3, 2 and 1 grids. If too low electricity, the instrument will automatically shut down.
3、Gravity acceleration setting function: users can input the exact value of gravity acceleration at their discretion to allow the test more precise.
4、Peak value maintaining function: maintain the peak value display until zero adjustment manually.
5、Automatic peak function: Maintain to display the peak values for 2 s before automatically elimination.
6、Large memory storage function: can store 896 test values.
7、Data output function: data can be input in the computer for various analyses through data links
